McMillan & Wife Season 5 Episode 4

Mac: (reading blackmail letter) You really are a swinger.
Sally: Uh-huh. A promiscuous swinger.
Mac: Uh. The worst kind.

Sally: It says there that your wife is a promiscuous swinger and a user of drugs.

Mac: Don't talk about this in the house. Remember the bug in the plant.
Sally: I know, I watered it!

Mac: How was lunch?
Sally: I didn't touch a bite of it. How about you?
Mac: Oh, I had a bit of it. It bit back.

(The MacMillans' house is bugged.)
Sally: How can you make love when you know that someone's listening in?
Mac: Very quietly.

Mildred: You can't win around here! Will someone please tell me where my loyalty lies?
Mac: Who writes your check every week?
Mildred: A telling point.

Mildred: (on telephone) Commissioner McMillan, please. Tell him it's meddler call-uh, Mildred.

Sally: "Where there's smoke, there's fire!"
Mac: Exactly. It's a bromide men in public office have learned to respect.

Danziger: We also take on some government work from time to time. It can get a little cloak-and-daggerish.
Enright: (grinning) Well, that should keep things interesting!

Enright: Well, to tell you the truth, Sir, my first relationship with a girl wasn't very eventful.
Danziger: So I've been told.

Maggie: So you're not going to push some... preference on me?
Mac: Have I ever pushed some... preference on you before?
Maggie: Mrs. McMillan always has a very strong opinion.
Mac: Not this year.
Maggie: Why?
Mac: She forgot to register.
